A well-trained honey bee scientist wouldn’t spell the name “honeybee”, even though you’ll find it mistakenly spelled this way in a number of dictionaries (as well as on the MS spell checker), and even in Wikipedia. The biological convention is that the name of an insect is separated into two words when the insect is what the name implies. So “honey bee” is separated into two words, since its a bee that collects honey, whereas “butterfly” is one word since it isn’t a fly that produces butter.

So is a bumble bee a bee that bumbles or is she just a bumblebee?
And what about beer bees?
